3.19. Signal Delay
With the system, you can set the signal delay time or pulsewidth for the various signals that are input
and output. Pulse width and delay settings for the various signals to input/output are made with PFV
or the LCD remote controller (optional). The content of each setting is listed in the chart below.
Setting Item Setting Range (Value)
TRIG TTL IN DELAY 0-60 (s) 100 ns units
SYNC IN DELAY 0-1/frame rate (s) 100 ns units
GENERAL IN DELAY 0-60 (s) 100 ns units
TRIG OUT WIDTH 0-1 (ms) 100 ns units
SYNC OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT WIDTH 0-500 (us), 1/frame rate (s) at 2000 fps or higher 100 ns units
EXPOSE OUT DELAY 0-1/frame rate (s) 100 ns units
SYNC OUT TIMES 0.5, 1, 2, 4, 6, 8, 10, 20, 30 ( * x1 is standard output)
SYNC OUT TIMES
Outputs SYNC (vertical synchronization signal) from SYNC OUT that is X times SYNC.
Example: For a frame rate of 1000 fps, SYNC OUT TIMES setting of 2.
Example: For a frame rate of 1000 fps, SYNC OUT TIMES setting of 4.

When the frame rate is set to 48,000 fps or higher, x30 cannot be set.

When the frame rate is set to 96,000 fps or higher, x20 and x30 cannot be set.

An accurate frequency is output, but when SYNC OUT TIMES is set to a large value with a high
frame rate, the setting may result in frequency errors.
